Struct gdk4::TextureDownloader
source · #[repr(transparent)]pub struct TextureDownloader { /* private fields */ }
v4_10
only.Expand description
The TextureDownloader
is used to download the contents of a
Texture
.
It is intended to be created as a short-term object for a single download, but can be used for multipe downloads of different textures or with different settings.
TextureDownloader
can be used to convert data between different formats.
Create a Texture
for the existing format and then download it in a
different format.
Implementations§
source§impl TextureDownloader
impl TextureDownloader
sourcepub fn as_ptr(&self) -> *mut GdkTextureDownloader
pub fn as_ptr(&self) -> *mut GdkTextureDownloader
Return the inner pointer to the underlying C value.
sourcepub unsafe fn from_glib_ptr_borrow<'a>(
ptr: *const *const GdkTextureDownloader
) -> &'a Self
pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const GdkTextureDownloader ) -> &'a Self
Borrows the underlying C value.
sourcepub unsafe fn from_glib_ptr_borrow_mut<'a>(
ptr: *mut *mut GdkTextureDownloader
) -> &'a mut Self
pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut *mut GdkTextureDownloader ) -> &'a mut Self
Borrows the underlying C value mutably.
source§impl TextureDownloader
impl TextureDownloader
sourcepub fn new(texture: &impl IsA<Texture>) -> TextureDownloader
pub fn new(texture: &impl IsA<Texture>) -> TextureDownloader
sourcepub fn download_bytes(&self) -> (Bytes, usize)
pub fn download_bytes(&self) -> (Bytes, usize)
Downloads the given texture pixels into a GBytes
. The rowstride will
be stored in the stride value.
This function will abort if it tries to download a large texture and fails to allocate memory. If you think that may happen, you should handle memory allocation yourself and use gdk_texture_downloader_download_into() once allocation succeeded.
Returns
The downloaded pixels.
out_stride
The stride of the resulting data in bytes.
sourcepub fn format(&self) -> MemoryFormat
pub fn format(&self) -> MemoryFormat
sourcepub fn set_format(&mut self, format: MemoryFormat)
pub fn set_format(&mut self, format: MemoryFormat)
Sets the format the downloader will download.
By default, GDK_MEMORY_DEFAULT is set.
format
the format to use
sourcepub fn set_texture(&mut self, texture: &impl IsA<Texture>)
pub fn set_texture(&mut self, texture: &impl IsA<Texture>)
